Driving and operating145
The boiling point depends on the
pressure and mixing ratio. At ambient pressure, it is between -42 °C (pure
propane) and -0.5 °C (pure butane).Caution
The system works at an ambient
temperature of approx. -8 °C to
100 °C.
Full function of the LPG system can
only be guaranteed with liquid gas
which complies with the minimum
requirements of DIN EN 589.
Fuel selector
Pressing the LPG button switches
between petrol and liquid gas
operation as soon as the required
parameters (coolant temperature,
gas temperature and minimum
engine speed) have been reached.
The requirements are usually fulfilled
after approx. 60 seconds (depending
on exterior temperature) and the first
firm press on the accelerator. The
LED status shows the current
operating mode.LED off=petrol operationLED illu‐
minates=liquid gas operationLED
flashes=no switching is
possible, one type of
fuel is empty
As soon as the liquid gas tanks are empty, petrol operation is
automatically engaged until the
ignition is switched off.
Every six months, run the petrol tank down until control indicator Y
illuminates, then refuel. This helps
maintain fuel quality and system
function for petrol operation.
Fill the tank completely at regular
intervals to prevent corrosion in the
tank.
Faults and remedies
If gas mode is not possible, check the following:
■ Is there enough liquid gas present?
■ Is there enough petrol present for starting?
Due to extreme temperatures in
combination with the gas
composition, it may take slightly
longer before the system switches
from petrol to gas mode.
In extreme situations, the system may
also switch back to petrol mode if the
minimum requirements are not
fulfilled.
Seek the assistance of a workshop in the event of all other faults.

Accessories and vehicle
modifications
We recommend the use of genuine parts and accessories and factory
approved parts specific for your
vehicle type. We cannot assess or
guarantee reliability of other products
- even if they have a regulatory or
otherwise granted approval.
Do not make any modifications to the electrical system, e.g. changes of
electronic control units (chip tuning).Caution
When transporting the vehicle on
a train or on a recovery vehicle, the
mud flaps might be damaged.
Vehicle storage
Storage for a long period of time
If the vehicle is to be stored for several months:
■ Wash and wax the vehicle.
■ Have the wax in the engine compartment and underbody
checked.
■ Clean and preserve the rubber seals.
■ Fill up fuel tank completely.
■ Change the engine oil.
■ Drain the washer fluid reservoir.
■ Check the coolant antifreeze and corrosion protection.
■ Adjust tyre pressure to the value specified for full load.
■ Park the vehicle in a dry, well ventilated place. Engage first orreverse gear. Prevent the vehiclefrom rolling.
■ Do not apply the parking brake.
